Diagnoses.
Peridinetus illabes
is one of several species with red anterior, black median and olive posterior portions. Five of them have a large, black, semicircular area on the elytral base and plumose setae in the prosternal channel.

is the only species without a patch of white setae on the elytral flank (
Fig. 36
). Females have the dorsal rostral groove near the basal third (
Fig. 44
); males have the antenna inserted near the distal fourth (
Fig. 36
; more basally in all other species).
